This use was explained by several previous studies where antimicrobial, antifungal, anti-HIV and anti-cancer and antioxidant compounds were isolated from several Calophyllum species. Approach: The leaves were extracted with n-hexane (hexane), dichloromethane (DCM) and methanol using soxhlet apparatus. Total phenolic contents of each … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,623 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFungal Culture Systems for Production of Antioxidant Phenolics Using Pecan Nut Shells as Sole Carbon SourceMiguel A. Medina, Ruth E. Belmares, Antonio Aguilera-Carbo et al.Problem statement: Many agro-industrial wastes have little or none utilization, when these materials could be a very rich source of several value-added compounds, such as: the pecan nut shells, which contain Antioxidant Phenolic (AP) molecules like tannins. Approach: In this study, a bioprocess for the liberation of AP from Pecan Nut Shells (PNS) was described. A chemical characterization of raw … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,042 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpiral Wound Reverse Osmosis Membranes for the Recovery of Phenol Compounds-Experimental and Parameter Estimation StudiesG. Srinivasan, S. Sundaramoorthy, D.V.R. MurthyProblem statement: Reverse osmosis is increasingly used as a separation technique in chemical and environmental engineering for the removal of organics and organic pollutants present in waste water. The removal of an organic compound, namely phenol, using a polyamide membrane was investigated in this study. Waste water containing phenol present a serious environmental problem and increasing attention is being given … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,304 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Inhibition of Human Pathogens: Trichophyton rubrum and Trichoderma harzianum by a Natural ProductRand R. Hafidh, A.S. Abdulamir, Law Se Vern, Fatimah Abu BakarProblem statement: A number of studies have recently conducted to identify novel and potent antifungal components from natural products. One of the reasons is to overcome the antifungal resistant developed against most of commercially available drugs. Studies confirmed that mung beans have increased phenolic compounds and enhanced defenses during germination. Approach: We hypothesized that antifungal activities might be found in … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 9,361 accessesView PDF Cite

Research ArticleOpen accessIn the abstractControl of Phenolic Compound Secretion and Effect of Growth Regulators for Organ Formation from Musa spp. cv. Kanthali Floral Bud ExplantsSoubir Titov, Salil Kumar Bhowmik, Ajoy Mandal et al.The study was undertaken to examine banana cv. Kanthali floral bud apex as an alternative source material for in vitro propagation because huge number of explants die due to microbial contamination in case of shoot tip explants. Contamination free cultures were established by treating the floral bud explants with 0.1% HgCl2 for 6 min. This study found that inflorescence tissues … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 3 · 30 Sep 2006 · 7,742 accessesView PDF Cite
